In his recent New York Times bestseller “Trumpocracy: The Corruption of the American Republic,” David Frum, senior editor of The Atlantic, lays out a compelling account of how President Donald Trump’s tendencies could push the United States toward the illiberalism that many Americans believe the republican system of government to be immune to. In an event on Feb. 7 at the Brookings Institution, Frum sat down with Jonathan Rauch, Elaine Kamarck, and Lawfare’s Benjamin Wittes for a conversation and Q&A on the book and Trump’s threats to democracy.
